na mention mo na kahit sa hway meron ka naririnig, you have to fix that. pinging sound indicates that the fuel is being burned way before the piston reaches its top cycle. it will lead to overheating of the cylinder head and cause other kinds of problems you dont want to have.

kung nasa timing naman ang makina mo, you can check on the carb if its carb type, and have it tuned up (look at the spark plug, air filter, fuel filter and as they suggested contact point kung meron ang dizzy mo) also have the valve clearance inspected kung within specs pa.

using higher octane fuel may help as stop gap measure.
